I've never performed a series of this many colonics in such a short period of time. To me it is clearly excessive, and something I would not recommend.
I have had clients who needed sessions twice a week for 2 to 4 weeks, followed by once a week for several weeks, then once every 2 weeks for a while and finally maintenance once a month. But for a series of 11 colonics, the shortest period of time I can imagine doing that would be over about a 2 to 3 month period. I often do recommend enemas in between colonics as needed to maintain regularity though.
